IMPROVEMENT IN PRINTERS GALLEYS.

Specification forming part of Letters Patent No.

216,689, dated June 17,1879; application filed April 7, 1879.

To all whom it may concern Beit known that I, THOMAS T. MGNISH, ofAllegheny, in the county of Allegheny and State of Pennsylvania, haveinvented a new and useful Improvement in Printers Galleys; andI dohereby declare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawings, forming apart of this specification, in which--- U t Figure 1 is a plan view ofthe blank from which my improved galley is made. Fig. 2 is a perspectiveview of my improved galley.

Like letters of reference indicate like parts in each.

My invention consists in a printers galley formed from a single piece orblank of sheetsteel or other suitable metal, by cutting two of thecorners of the blank so that when the edges of the blank are turned upto form the sides and end of the galley a tongue or tongues on the sideswill lap over the end wall of the galley, and tongues upon the end willlap over the side walls, thus perfectly supporting the side and endwalls against both external and internal pressure, and this Without thenecessity of either welding, soldering, or riveting the parts.

Heretofore printers galleys have been made either of wood or of brass,or of a combination of wood and brass. Those which are formed wholly orpartially of wood are subject to warp-- age, on account of beingfrequently wet, and sooner or later become untrue from that cause, andconsequently unfit for use. Those which are formed of wood lined withbrass are not only liable to warp, but to injury from the alkali andwater used in cleaning the type, by their eating in around the screwsand causing the brass linings to become loose. Those which are madeentirely of brass are too expensive,'because brass is not only costly,but is a soft alloy, and in order to obtain sufiicient strength in thewalls to prevent their being bent out of shape they must be made veryheavy. The great expense of an all-brass galley has been much reduced byan invention of mine, (for which I have obtained Letters Patent- No.214,832, dated April 29, 1879,) by

j which sheet-brass may he used alone, the walls being formed by foldingthe sheet upon itself in order to obtain the requisite strength andstiffness.

Brass has heretofore been the only metal re-' garded as suitable, in aneconomic and practically useful point of view, to the construction ofprinters galleys. Of other metals and alloys, some were too heavy, sometoo soft, some too expensive, and others not only too heavy, but alsosubject to corrosion.

I have found that sheet-steel is peculiarly adapted for use in theconstruction of galleys. It has the following properties, which fit itespecially for that purpose: It is light, and at the same time verystifl and strong, and can be bent into shape without injury. For thisreason the side and end walls can be made of a single thickness, and theentire galley of one piece, the walls being formed by turning up theedges at right angles. It is susceptible of being coated to resistcorrosion from the water and lye. It is extremely cheap, costing lessthan one-half the price of sheet-brass, and, lastly, it can be cut andbent to shape at small cost.

For the above reasons I prefer to make my galley of sheet-steel, and toprotect it bycoating or plating it, as will hereinafter appear,

though I do not limit myself to the use of sheetsteel, either coated orotherwise, as any suitable metal may be employed.

I cut the blank to and tongues c and c from the sheet of steel, andscale it perfectly by pickling and grinding. 1 find that grindingis themost certain way of obtaining a perfect removal of the scale. The sideand end walls, I) and c, are formed by turning up the edge of the blanka at right angles. The corners d are jointed, as in Fig. 2. Thejointat din Fig. 2 is a very'simple and strong one. The lower lug, c, lappingaround the end wall, prevents the side from being forced in and the endfrom being forced out, and the upper lug, a,

being sprung or spread outward and the end from being forced inwardly,while the plain inner surface of the walls remains unbroken, which is anecessary feature in a galley.

After the galley has been bent into shape it is coated with a permanentcoating, for the lapping around on the side, prevents it from i purposeof protecting it from corrosion arising. from its being frequently wet,and from being handled by the perspiring hands of the typo. This may bedone with nickel or other like metal by electro-deposition. or bydipping in zinc, platinum, or tin, or by japanning or baking on avitreous coating, or-by coating with magnetic oxide.

The simplicity of the form, cheapness, and suitability of the materialfor this purpose enable me to produce this galley at much less cost thanany of the various forms of brass or brass-lined galleys heretoforeknown, while, on the other hand, it is absolutely free from thebefore-mentioned objections to the wood, brass, and brass-lined galleys.

What I claim as my invention, and desire to secure by Letters Patentfis-A printers galley made of a single piece of sheet metal, the side andend Walls of which are formed by turning up the edges at right angles,and the corners of which are locked or secured by tongues which lap overon both the end and side walls, substantially as and for the purposespecified.

In' testimony whereof I, the said THOMAS 'l. MONISH, have hereunto setmy hand.
